SKYLIGHT.

Application filed January 5, 1924.. Serial No. 684,651.

To all whom it may concern.

Be it known that ALFRED lVInLvILLn JAMES, a subject of the King of GreatBritain, residing at Dunedin, in the Do minion of New Zealand, hasinvented certain new and useful Improvements in and Relating toSkylights of which the following is a specification. g

This invention relates to skylights such as are ordinarily used inconjunction with buildings and for other similar purposes and has forits object to provide a skylight of a simple yet strong and efficientconstruc tion and in which there are no small grooves or condensationchannels which are so positioned that they become ineffective throughbeing choked with dirt and the like. The invention is adapted to be madewith or without ventilating means as may be desired.

The invention consists in the features and arrangements and combinationsof parts hereinafter described and more particularly pointed out in theclaims.

Referring to the accompanying drawings which illustrate the preferredembodiment of the invention Figure 1 is a general perspective view ofthe improved skylight shown partly in section to illustrate theconstruction, Figure 2 is an enlarged cross sectional elevation of oneof the sides showing the details of construction, Figure 3 is anenlarged part outside elevation of one of the sides as shown in Figure2. Figure 4 is an enlarged cross sectional view of a supporting barshowing the method of construction, Figure 5 shows a modification of theconstruction of the said supporting bar shown in Figure 4. It will beseen that the improved skylight preferably comprises four sides 1 ofgalvanized sheet metal or other similar material which may be made allin one piece. These sides 1 are bent at right angles at their lower endsto form the usual base flashing 2 which is secured to the roof or thelike in any usual manner. The end edges 3 of the bent side 2 may ifdesired be lead edged.

The upper parts 4 of the sides 1 are bent inwardly and are doubled at 5as is clearly shown in Figure 2 to form a condensationgroove 6 whichprevents any driving rain from getting inside and also stops any directdown draft. The portions 7 of the sides 1 are provided with ventilationholes 8 and bent at their upper extremities to form grooves 9 which aredesigned to receive an asbestos packing cord 10.

Stifliening bars 11 are secured where necessary to the sides 1 by rivets12 or other suitable means and these stiffener bars 11 are provided withan outwardly projecting flange 18 which is then turned ver- -ticallyupwards again at 13. To the portion 13 of this stiffening bar 1.1 and tothe flashing 17 on two sides and at the back of the skylight ispreferably secured a flat strip of metal 141 by means of countersunkrivets 15. The glass 16 rests upon the asbestos cord 10 and is heldsecurely in position by the flashing 17 which is secured to thehorizontal portion 18 of the stiffener 11 by bolts 19.

At the lower end of the skylight or elsewhere stiifeners or supports 35are secured by rivets 12 to the side 1 which act as stiffeners to theupper portions 7 of the sides land these also prevent the glass fromslipping.

A glazing bar 20 of which more than one may be used where necessary maybe provided. This bar is not necessary where the skylight is narrow. Thebar 20 see'Figiizre 4, is constructed with a bottom bent up to form twosides 21 which are bent outwards and doubled back, and riveted as at 27to form condensation channels 22 the upper end-=1 23 being bent to formgrooves 24 in which are placed asbestos cords 10 upon which the glass 16rests. Ventilation holes 25 may be provided on each side. U shapedstiffening brackets 26 are provided at suitable intervals and areriveted with rivets 27 to the inner sides 23 of the centre bar 20. Thepanes of glass 16 are secured by means of flashing 29 which is securedto the stiffener brackets26 by means of bolts 28. The bar 20 is securedby being sweated or otherwise to the sides 1 of the skylight so that thewater in the condensation channels 22 passes into the main condensationchannel 6 and hence tothe roof by any suitable orifice such as forinstance the ventilation holes 8.

In a modification of the central bar 20 as shown in Figure 5, noventilation holes are provided and the sides 21 of the said bar 20 aredeepened and are riveted to U shaped stiffening brackets 30. Thecondensation channel is constructedas shown in Fi ure 1 the upperextremities 31 of the si es 21 being bent tofo'r'rn agroove to receivethe asbestos cord 10 The bolt 32 securing the flashing 29 to the bracket30 is bent at its lower end in a right angular direction and is providedwith a shoulder 33, the end 34 passing through the sides 21 and 80 ofthe bar 20 and bracket 30 respectively and then secured by a rivet 35 orother suitable means.

I claim 1. A skylight having sides with the lower ends thereof bent toform a flashing said sides being also so formed within the skylight asto provide condensation channels said sides further having their upperedges turned over to form a groove and seating for an asbestos cord,stittening bars secured to and adapted to strengthen said sides saidstiffening bars being bent horizontally outwardly and then again bentvertically up- Wards a sheet of glass adapted to rest on said asbestoscord, a flashing adapted to secure said sheet of glass firmly inposition said flashing being secured to the horizontal portion of saidstiffening bar substantially as describedand for the purposes set forth.

2. In a skylight having sides Whose lower ends are bent to form aflashing and being so formed Within the skylight as to providecondensation channels, the combination With at least one'substantiallyU-shaped glazing bar the sides of which are formed to providecondensation channels and the upper edges of Which are bent to formgrooves, of substantially U-shaped stiffening brackets secured to saidbar, asbestos cord in said grooves, a cover for the skylight supportedby the asbestos cord, and aflashing secured to the stiffening bracketsand adapted to hold the cover iirinly in position.
